The key points of the review of the senior one geography exam, and the compulsory content of the hig

The amount of geography that students know is not based on how much geography knowledge students can memorize, but on how much relevant geography knowledge they can extract from a map or a piece of material, and how much geography knowledge they can expand. Therefore, in the review process, it is not for students to memorize geography knowledge, but to learn geography from the most primitive learning method of "looking at pictures and talking".

Personally, I think the focus should be on industry. Agriculture. Traffic. This unit.

For example, the location selection of industry and agriculture, and the mode of transportation.

The compulsory content of the high school geography examination is as follows:

1. The level of the celestial system:

Total galaxies – Milky Way (extragalactic galaxies) – Solar system (other star systems) – Earth-Moon system.

2. The conditions for the existence of life on Earth

External: Stable sunlight conditions, relatively safe cosmic environment.

Self: Because the distance between the sun and the earth is moderate, the surface temperature is suitable (the average temperature is 15 degrees).

3. The impact of solar activity on the earth

1) Signs of solar activity: sunspots, flares, 11-year cycle; Impact: Sending out positive and quiet magnetic waves affecting the ionosphere – interfering with radio shortwave communications; emitting high-energy charged particles – generating the phenomenon of "magnetic storm" and "aurora"; Affect the earth's climate, disasters - flood and drought disasters, induced.

4.Characteristics of rotation and revolution

5. The geographical significance of the Earth's rotation

Alternation of day and night: the dividing line between the day and night hemispheres - the morning and dusk lines (circles) - the time of the intersection with the equator are 6 o'clock and 18 o'clock respectively - the height of the sun is 0 degrees - the flat digging plane where the morning and dusk circles are located is perpendicular to the sun's rays;

Local time difference: morning in the east and evening in the west, longitude varies by 1 hour every 15 degrees. Geostrophic deflection force: no deviation on the equator, right deviation in the northern hemisphere, left deviation in the southern hemisphere.

6.Changes in the length of day and night

In the summer half of the northern hemisphere, the sun shines directly on the northern hemisphere, and the days and nights are short at each latitude in the northern hemisphere. On the summer solstice, the day length at all latitudes in the Northern Hemisphere reaches its maximum of the year, and the polar day phenomenon occurs in the Arctic Circle and the areas north of it.

From the summer solstice to the autumnal equinox, from the autumnal equinox to the winter solstice, the days are getting shorter and the nights are getting longer in the Northern Hemisphere.

In the winter half of the northern hemisphere, the sun shines directly on the southern hemisphere, and the nights are longer and the days are shorter at all latitudes in the northern hemisphere. On the winter solstice, day lengths at all latitudes in the Northern Hemisphere reach their lowest values of the year, and polar nights occur in the Arctic Circle and areas north of it.

On the day of the vernal and autumnal equinoxes, the sun shines directly on the equator, and the length of day and night is equal to 12 hours each around the world. The equator equinoxes day and night throughout the year. The situation in the southern hemisphere is the opposite of that in the northern hemisphere.

7.Changes in the height of the sun at noon

On the summer solstice, the sun shines directly on the Tropic of Capricorn, and the height of the sun decreases from the Tropic of Cancer to the north and south at noon, when the Tropic of Cancer and its northern latitudes reach the maximum value of the year, and the latitudes of the southern hemisphere reach the minimum value.
